Wear clothes you are comfortable in, jeans and t-shirt are very normal
(plus a jersey at the start of cold winter nights), but more formal
clothes and dresses for the ladies are not out of place.
Although we don't have a strict dress code, we do expect that you are
tidily dressed and clean.

Shoes

Most shoes will work okay, even sneakers are perfectly fine to start
off with.
Most
lady's shoes with a flat sole or low to mid heel will be good to dance
in, but we wouldn't recommend a very high heel unless that's what you
wear every day. Just make sure the tip of your heal is not too small
(<1x1cm) as this can damage our floor. If in doubt bring a spare
pair and just ask at the counter.
For
the guys we recommend a shoe that will give you a bit of slip
on
the floor such as a leather or other smooth soled dress shoe or maybe even a
proper dance shoe if you start getting a bit serious about it.
About the only footwear we wouldn't recommend are jandals or stiletto
heels!
